VBWG IDEAL: The Incremental Decrease in End Points Through Aggressive Lipid Lowering Study
VBWG IDEAL: Study design Objective: To compare intensive vs less-intensive lipid-lowering therapies Design: Prospective, randomized, open-label, blinded end-point evaluation ( PROBE) Population: N = 8888 with previous MI Treatment: Atorvastatin 80 mg, simvastatin mg/d Primary outcome: Coronary death, nonfatal MI, resuscitated cardiac arrest Secondary outcomes: Major CVD (primary event, stroke), CHD (primary event, coronary revascularization, hospitalization for UA), any CVD (any of the above, PAD, hospitalization for CHF), all-cause mortality Follow-up: Median 4.8 years Pedersen TR et al.

VBWG IDEAL: Summary High-dose atorvastatin vs usual-dose simvastatin in post-MI patients: Trend to benefit in primary outcome (11% RRR) Significant reductions in composite secondary outcomes (13% to 16%) No difference between groups in all-cause or CV mortality No difference between groups in serious adverse events – Incidence of liver enzyme elevation with atorvastatin was <1% and comparable with results of other trials 4 studies now support aggressive lipid lowering to reduce CV events in high-risk patients: IDEAL, PROVE IT-TIMI 22, A to Z, TNT Pedersen TR et al.
